Best electricity and gas providers in SA

Here are our picks for the top 10 electricity and gas providers in South Australia, rated on number of customers, percentage of complaints and basic plan cost.

These are subjective picks and what you rate as "best" may differ.

• How did we choose the best energy providers in South Australia?

  We analysed data from the Annual retail markets report (2019–2020) and looked at complaints to the 10 largest energy retailers available in SA.
  
  We used price, complaints and popularity (number of customers) to rank the providers. The weighting used against each to determine rankings was:

  • Basic plan price: 40%
  • Complaints: 40%
  • Popularity/number of customers: 20%

  The prices we've used (true as of 19 November 2021) are based on a residential customer in Adelaide using the postcode 5000. This assumes the customer will consume 3,900kWh a year on a single rate tariff on the SA Power Networks.
  
  Our estimated prices include conditional discounts, such as pay on time discounts. Your actual bill will depend on your usage.
  
  Providers that offer both power and gas are only differentiated by plan price and customer numbers – complaints are for the provider as a whole.

How much can I save by switching energy plans?

There are 2 common scenarios where you can save money by switching:

• You're on a standing offer. If you've been on your plan for over a year or have moved house recently, there's a chance you're on a standing offer. The latest research indicates you could save between $180 and $300 per year by switching to a market offer.
• You haven't compared recently. Even if you're on a market offer, there's a good chance there's something cheaper on the market since you last switched. Switching in this case can still save you money.

Regardless of your situation, all you need to do is compare energy plans available in your area to see what you can save.

Energy rebates come in 2 forms: a flat sum or a percentage of your bill. To claim a rebate, you'll need to meet certain eligibility requirements, such as holding a valid concession card.
